Combine half the garlic, the seasoned salt, and the pepper. Pat the meat dry and rub with the garlic mixture.

Sear the steaks in a large skillet with 2 tablespoons of the butter until brown on the outside with the center raw. Arrange the steaks in a 13 X 9 inch baking dish.

Pour the brandy into the skillet and stir over moderate heat, scraping up the brown bits. Add remaining 4 tablespoons of butter. When the butter is foaming, add the mushrooms and cook until browned, about 5 minutes. Stir in the flour and reduce heat to low. Stir in the tomato paste and remaining garlic.

Remove from the heat; whisk in the wine, chicken broth, beef broth, and water. Bring to a boil over moderate heat, stirring constantly. Reduce heat and simmer 10 minutes, until the liquid is reduced by a third.

Add Worcestershire and currant jelly. Adjust seasonings to taste and thin the sauce to a coating consistency.

Cool and pour over steaks. (At this point steaks may be covered and refrigerated overnight. Allow them to come to room temperature before cooking.).
